Combination Gun
Definition
A firearm combining barrels for different ammunition or bore arrangements, such as a rifle and shotgun barrel. Evidence from different barrels can come from one platform. Each chamber and relevant firing or extraction components need separate documentation and appropriate comparison.
A combination gun incorporates barrels for different ammunition or bore arrangements on one firearm. A two-barrel rifle/shotgun combination and a three-barrel drilling are examples. Record every barrel, chamber, selector and relevant component rather than assume one fixed layout.
